TUNAP Diesel Particulate Filter Cleaning

microflex® 931 (incl. 932)

The cleaning set for diesel particulate filters (DPF) consists of a nonflammable and metalfree cleaning liquid and a rinsing solution. The process developed and patented by TUNAP functions without time-consuming removal of the DPF.

Cleaning without disassembling the particulate filter

Nonflammable

Neutral ash- and metalfree formulation

Residue-free evaporation

Material compaibility

Satisfied Customers, satisfied workshops!

"We had very successful results! The DPF was so clean it did not need to be regenerated. This provided the customer with a reconditioned DPF for a fraction of the renewal cost."

Clive C. from Hadlow Stair Garage

"The DPF limit was reached and it could not carry out regeneration. After using the TUNAP DPF Cleaning the regeneration started and the car was running and performing normally. Very happy with the results!"

Kieran B. from T.O. Bassett & Sons

"We are highly delighted with the successfull results! TUNAP also offers very good training and support."

Rob K. from Go Vauxhall lewisham

Application

Dirty particulate filter

Before

The electronic indicator lights, the vehicle has no more power and an extremely high fuel consumption? The diesel particulate filter has only a limited capacity to store particulates. From a certain amount of soot, the soot particles must be burned in a regeneration process to CO₂ and ashes. Different reasons can cause the regeneration process does not start and in consequence the DPF gets clogged with soot particles.

Application

TUNAP pressure cup spray gun

Remove the pressure sensor or disconnect the filter from exhaust pipe and instert the spraying probe into the opening made with the direction of spraying towards the particulate filter. Flush out the particulate filter after cleaning using the flushing concentrate. Reinstall the pressure sensor or assemble the filter to the exhaust pipe and allow the engine work with varying speeds for approx. 15 minutes. At the end perform a test drive of at least 30 minutes and start the filter regeneration manually using the tester, if necessary.

Cleaned particulate filter

After

TUNAP is the first manufacturer to have developed a patented particulate filter cleaning system with which clogged particulate filters can be cleaned in an installed condition, rapidly, simply and significantly more economically than replacing them.

Against causes

microflex® 926

The innovative XFoam-technology detaches persistent contamination in the exhaust and/or air intake system.

Against causes

microflex® 984 & 989

984 protects injectors from fuel-induced deposits and lowers fuel consumption and emissions to original factory levels. 989 removes from injectors any fuel-related sediment such as deposits of carbon or resin.

Protection

micrologic® PREMIUM 184

System Ingredient for all diesel engines with serial and aftermarket installed Diesel Particle Filter. Reduce burn off temperature of the soot in the Diesel Particle Filter caused to adverse drive profile.

TUNAP benefits!

Satisfied Customers

The exact saving depends on the particulate filter that is installed. New particulate filters cost approximately £ 1,000 to £ 2,500, and in many cases much more. TUNAP particulate filter cleaning costs between £ 300 and £ 400, depending on the vehicle and service station. In many cases, you can save £ 1,000’s.

No expensive removal

TUNAP particulate filter cleaning takes place via the inlet of the temperature sensor. The blocked particulate filter is rinsed clean with the special probe. Soot deposits in the particulate filter are removed thoroughly without dismantling the filter.

More than 250.000 times tested successfully

With innovations and reliable products from our R&D and production and with our comprehensive international direct sales organisation TUNAP is successful and indispensable partner of several industries. More than 30.000 customers are using TUNAP products and systems.

Patented technology

TUNAP inspires with innovative developments and system solutions in the field of chemistry. As the technological market leader in the section automotive TUNAP offers development, production and sales from one source.

Proven efficacy (VERT)

The VERT® Association (Verification of Emission Reduction Technologies) is an association dedi-cated to the identification and promotion of best available technologies for emission control. Mem-bers of the VERT® Association include international engine manufacturers and manufacturers of particulate filters and SCR systems.

Proven safety (TÜV)

The chemicals used in TUNAP particulate filter cleaning do not affect components in the exhaust system. This has been tested and confirmed by the German technical inspection authority TÜV Thüringen. If the product is used as intended, the particulate filter cannot suffer any mechanical damage, as the system works with a pressure of approximately 2 bar. The components of SCR and NSC catalysts (mainly installed in EURO 6 vehicles) are also not adversely affected.

FAQ

Frequently asked questions about the TUNAP DPF cleaning

Why do particulate filters get blocked?

There are various reasons for blocked particulate filters. The most common are:

Sooty/dirty injectors

Dirty EGR system

Fluctuating fuel quality

Unfavourable driving profile: The vehicle is not driven on long journeys, with the result that the filter is not regenerated

What particulate filter cleaning methods are available?

Cleaning the particulate filter while it remains in place (TUNAP diesel particulate filter Cleaning)

Removing the particulate filter to clean it

How long does the particulate filter remain clean?

Particulate filters cleaned with the TUNAP system are comparable to new particulate filters. To ensure that the particulate filter functions for a long time, you must find and eliminate the reasons for the blockage, otherwise the filter could clog up again.

Can the TUNAP particulate filter cleaning fluid burn?

TUNAP particulate filter cleaning fluid is not flammable.

Who verifies the effectiveness of TUNAP diesel particulate filter cleaning?

The VERT® Association verifies and recommends the effectiveness of the TUNAP particulate filter cleaning process.

When do I have to replace the particulate filter?

Generally, particulate filters only have to be replaced if components are actually defective. When filters are blocked or sooty, it is sufficient to clean the filter.

What does particulate filter cleaning have to do with SCR and NSC catalysts?

Basically, SCR and NSC catalysts have nothing to do with particulate filter cleaning. These com-ponents are installed in newer vehicles (mainly EURO 6) to reduce nitrogen oxide (NOx) emis-sions. When the particulate filter is being cleaned, they only come into contact with the TUNAP cleaning fluid when it is being discharged.

How can I prevent renewed blockage of the particulate filter?

To prevent renewed blockage of the particulate filter, you must eliminate the causes of the blockage:

The quality of the fuel varies from garage to garage. Regular addition of microflex 984 Injector Direct Protection can prevent contamination in the injectors.

Drive longer distances (preferably on motorways) with more strain on the engine. Regular use of the micrologic 184 Particulate Filter System Ingredient can also prevent blocked particulate filters, even with unfavourable driving profiles.

Is TUNAP particulate filter cleaning environmentally friendly?

During TUNAP particulate filter cleaning, the soot deposits in the particulate filter are dissolved and are then burned to form CO₂ during normal regeneration of the filter. There are no additional impacts for the environment. We also prevent the environmental damage that arises from the manufacture of a new particulate filter. For example, through raw material extraction and the enor-mous energy consumption during the manufacture of a new part.
